由于以下原因，预渲染失败:ReferenceError:未定义窗口 [英] Prerendering failed because of error: ReferenceError: window is not defined

问题描述

我是 Angular2 的新手，我正在尝试通过演示项目进行功能测试并使用预渲染在代码中使用 Webpack .

I am new in Angular2, I am trying to go through functionalities with a demo project and used prerendering with Webpack in the code.

我的代码在这里-

https://github.com/abrarjahin/Dot.NetCore_Angular2_App

我收到此错误-

An unhandled exception occurred while processing the request.

我从未在代码中使用任何窗口.

I never used any window in my code.

有人知道为什么我会收到此错误吗?

Does anyone have any idea why I am getting this error?

我已经检查了这个问题- AngularJS ReferenceError:未定义$ window

I had checked this question - AngularJS ReferenceError: $window is not defined

但这没有帮助.

预先感谢您的帮助.

推荐答案

导入npm模块时，我遇到了同样的问题，我通过替换Index.cshtml页面上应用程序组件的prerender属性来解决此问题:

I had the same issue when import npm modules, I fixed this by replacing prerender attribute for app component at Index.cshtml page:

<app asp-prerender-module="ClientApp/dist/main-server">Loading...</app>

到

<app asp-ng2-prerender-module="ClientApp/dist/main-server">Loading...</app>

也许对您有帮助.
